Enumerate REST Response Header Names

See more REST Examples

Demonstrates Rest.ResponseHdrName, which returns the field name of the response header at a zero-based index. The example enumerates all headers, pairing each name with its value.

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

set rest = CreateObject("Chilkat.Rest")
bTls = 1
bAutoReconnect = 1
success = rest.Connect("example.com",443,bTls,bAutoReconnect)
If (success = 0) Then
    outFile.WriteLine(rest.LastErrorText)
    WScript.Quit
End If

success = rest.SendReqNoBody("GET","/api/items/123")
If (success = 0) Then
    outFile.WriteLine(rest.LastErrorText)
    WScript.Quit
End If

statusCode = rest.ReadResponseHeader()
If (statusCode < 0) Then
    outFile.WriteLine(rest.LastErrorText)
    WScript.Quit
End If

'  Enumerate the response header fields by zero-based index.  ResponseHdrName returns the field name
'  and ResponseHdrValue returns the value at the same index.
numHeaders = rest.NumResponseHeaders

For i = 0 To numHeaders - 1
    name = rest.ResponseHdrName(i)
    If (rest.LastMethodSuccess = 0) Then
        outFile.WriteLine(rest.LastErrorText)
        WScript.Quit
    End If

    value = rest.ResponseHdrValue(i)
    If (rest.LastMethodSuccess = 0) Then
        outFile.WriteLine(rest.LastErrorText)
        WScript.Quit
    End If

    outFile.WriteLine(name & ": " & value)
Next

outFile.Close
